Abstract: SiO₂/polyurethane (SiO₂/PUL) latexes modified by nano-SiO₂ (treated with γ-amino propyltriethoxy silane (KH550)) and end capped by hydroxyethyl methacrylate (HEMA) were first prepared through the prepolymer process.Then a series of nano-SiO₂/polyurethane-fluorinated polyacrylate (SiO₂/PUFA) hybrid latexes were synthesized via the seed emulsion polymerization process using hexafluorobutyl methacrylate (HFMA) as modifier, SiO₂/PUL as macromolecule emulsifier and seed emulsion.The properties of nano-SiO₂/PUFA emulsions and their films were characterized by Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), contact angle (CA),differential scanning calorimetry (DSC), thermogravimetry (TG) and tensile test machine.FT-IR characterization demonstrated that the polyurethane (PU) was successfully modified by modified nano-SiO₂ and HFMA.TEM result indicated that the nano-SiO₂ treated with KH550 was well dispersed in ethanol.Particle morphology of hybrid latex showed inverse core-shell structure, in which the core region was formed by acrylate (PA), while the shell region was formed by PU.TG result showed that the thermal stability of the latexes film was obviously improved by nano-SiO₂ particles.Water resistance and mechanical properties of nano-SiO₂/PUFA films were greatly improved due to the multiple cross-linking formed by modified nona-SiO₂ and fluorinated acrylate through the chemical bonds with polyurethane chains.

Key words: polyurethane, nano-SiO₂, fluorinated acrylate, core-shell structure, emulsifier-free emulsion
